The present invention is directed to a device which is adapted for theuse of training pilots or aviators, and familiarizing them with thevarious controls of the conventional type of airplane.

The device may also be adapted for the use-of an amusement device inwhich the operator of the same may manipulate the controls of theairplane for guiding the same Without the danger of a crash. One of the.important or primary objects ofthe present invention is to provide adevice in which an airplane is permitted to move bodily with respect tothe revolving struc-ture,- so that the operator thereof can guide, dip,dive, or bank the plane, and is permitted a wide rangeof control of theairplane within the limits of the range of the flexible cable connectingthe plane to the revolving structure.

A still further object of the invention isv to provide a novel andimproved aviator training device, amusement device, or toy, in which theconventional type of airplane is complete in every respect with theexception that the airplane is minus the propeller and the motor, and isheld in captivity or con-` nected with the revolving fra-me structurewith a flexible cable, which may be lengthened or shortened for varyingthe range lof the free movement of the airplane with respect to therevolving structure.

A still further object of the invention is tov provide a simplearrangement of an inclined braced trestle structure in the form of abeam, in which one end'thereof is pivoted to a post withthe intermediateportion thereof supported on a `truck adapted to travel on a circulartrack.

The description of my improved device 'will be directed to an aviatorstraining device, but it will of course be understood that t-he same maybe adapted as an amusement device or may be made in miniature form foruse as a toy.

These and other objects are accomplished by providing a construction andarrangement of thearious parts in the manner hereinafter described, andparticularly pointed ont in the appended claims.

Referring to the drawings,

Fig. 1 is a front elevational view of my improved aviator trainingdevice showing the cross section of the ground or support on which thedevice is mounted; and

Fig. 2 is an end elevational view of the 55 same.

In the drawings I have illustrated one embodiment of my invention whichis an improvement over the form of my invention described and claimed inmy co-pending ape0 plication Serial No. 342,959, filed Feb. 27, 1929, onDevice for training aviators or for amusement purposes.

In the drawings I have shown a trestle revolving structure comprising a.single beam generally indicated by the reference character 10, which ispreferably made of four sets of angle irons 11, which are securedtogether by steel plates 12 at the center thereof, at which point theyare held in relativelyspaced relation with -respect to each other, andconverged towards the other ends thereof, so as to form the effect oftwo tapered beams. .These angle members are suitably braced with crossbraces as indicated at 13 on the four sides 75 thereof. The inner end ofthe beam 10 is provided with a pivot bracket 14, which is securedthereto in any well known manner. This pivot bracket is ournalled on astud 15,

which in turn is imbedded as shown at' 16 in .80

a cement block or pillar 17. The cement block 17 is in turn imbedded inthe ground in any well known manner. Extending concentrically about thecement pillar 17 is a cement base 18 having a circular recess 19 inwhich a 85 circular track 20 is mounted. The revolving beam 10 issupported and sustained in an ini clined position of substantially 30,as shown in Fig. 1 of the drawings by a revolving truck generallyindicated bythe reference character 9 21. This revolving truck comprisesa platform frame structure 22, which is mounted on conventional form offlange car wheels 23. This truck is suitably braced and supported by-supplemental frame members 24. Each 95, of these wheels is driventhrough the medium of electric motors 25 supported to the substructureof the truck 21, geared to each of the 'respective wheels by means yofbelts 26.

Mounted on the platform 22 ofthe'truck 21 is I mi a control cabin 27 inwhich kthe operator may be seated for controlling the operation of thedevice. This truck 21 is provided withl two diverging reinforced framemembers as shown at 28, which have their upper ends suitably connectedto the beam in any well known manner. Each of these diverging end of thecable 32 is connected to the nose of.

the airplane ata point where the propeller would ordinarily be located.The airplane is of the regular type, and provided with the usualfuselage, wings, ailerons, rudder and tail, as well as the controls formanipulating the usual movableparts thereof so that the direction of theairplane is under the control of the operator seated in the fuselage.The airplane is also provided with a conventional form of landing gearso as to insure proper landing of the airplane on the ground when therevolving beam comes to rest. J

In the manner similarly described in my previous co-pending application,the length of the cable connecting the airplane with the revolving beammay be increased or diminished @so that the range of freedom of theplane with respect to the end of the beam ma be controlled by theloperator in the cabin 2g I ofthe truck 21.

From the above description it will be seen that when the operator in thecabin 27 connects or operates the control for driving the electricmotors 25, which in turn drive the truck Wheels 23, thebeam 12 will berevolved about its pivot 15, which in turn will cause the airplane torise from the'ground and Afollow the path described by the outer or freeend of the beam 10, and when sufficient speed is attained, .the operatorin the airplane may manipulate the controls for the purpose of banking,diving or doing other stunts vwithin the range of freedom permitted bythe cable. These various stunts maybe indulged in by the operatorwithout fear of a crash on account of the connection of the cable withthe free end of the arm or beam of the device.

From the above description it will also be seen that I have provided avery simple device in which by providing the inclined beam I haveeliminated the necessity of a large center standard structure as isrequired in my previous co-pending application, and as is disclosedinprior patents of this general conn struction. It will also be notedthat any number of these beams from one to six may be the same maysimilarly constructed and connected together about a single track, sothat a greater number of these devices or beams may be manipulated Ivbythe one operator.

While in the above specification I have described my device as beingparticularly adapted to'an aviators training device, it will of coursebe understood that the same is capable of use as an amusement device, orbe made in vminiature form with the t-ruck thereof driven by a springmotor, so that the principal features of my invention may be theembodiment of a-toy.

While in the above specification I have described one embodiment whichmy invention may assume, in practice it will of course be understoodthat the same is capable of modification, and that modification may-beemployed without departing from the spirit or scope of my invention, asexpressed in the following claims.

Whatk I claim as my invention and desire to secure by Letters Patent is:
